8 Claims.

The ordinary car window is hard toopen, due to the fact that. it is purposelyfgiven a tight t morder to make itwaterproof around the edges. l The principal object of this yinvention is to 5 provide an improved windowfor railway cars, buses and the like. which can be opened and closed easily, is absolutely water-tight when closed, and lcanbe manufacturedA at but little additional cost. .Y y

Other, morespeciiic objects and advantages of the invention will be apparent to those skilled in the'art upon a :full understanding of the con# struction, arrangement-and operation of the improvenient constituting the invention.

1 u Two different formsof the invention are presented herein by way of exempliiication, but it will of course be appreciated that the invention is capable of embodiment in `other structurally `in odiled formsv coming equally. within the scope ,20 of the appended claims.

. l ,The form of the 4invention killustrated `in Figs.

and the tightening member in itsY laterally re- (or 18s-'13) 1 to 7 inclusive will irst be described. In these views7 a sash 10 is shown'positioned in al frame sealing strips are adapted to ,engager and sealV with the opposed walls 18 of the projecting por- :tions 14 of the frame when the sash is in its lowermost position. Thetoprail 19 of the sash is provided on itsv outer face with a sealing strip 20, similar to the strip 17, for engagement with the header 2l of the frame, while the bottom .rail 220i the sash is provided at its lower edge with a rubber sealing strip 23 for engagement withr the sill 24 of the frame.

The sides of thesash, which are hollow, house a pair of automatically functioning tightening devices 25. Since both ofthe devices are the saine, only one will A-bedescribed in detail. It consistsr of a small finger 26 which is pivotedat 27 to a vertically movable carrier block 28. The block 28 is pressed downwardly by a coil spring 29 which is compressed between a flange 30 onfthe top of a stationary reinforcing channel -31 in the ystrap 33 attached to the sides ofA the-block. kThe channel 31 supports a .cam block 34 which is positioned between the'spaced sides of tliepslzrapvy sashand an abutment 32 on the top of a U-shaped sash opposite the same` are apertured at 36.

When the carrier block'28 is shifted upwardly in the channel 31 against the yielding resistance of Athespring 29, the roundedfupper free end of the finger' y26 will be cammed laterally out through the side aperture 36 by the beveled'face 359ithe cam block 34, as clearlyshowninFig. 5, and, when the carrier block 28fis shifted downwardly by the action of the spring 29,`the finger` 26 will f be retracted, as shown inFig. 6. The block 28 is provided at its lower end Ywith a threaded bore 37 in which the upper threaded end of a long vertically extending. rod 38 isscrewed. The rod 38 extends downwardly within the hollow side of the sash and emerges at the bottom through a hole. 39 in the adjacent end ofthe rubber sealing ,strip 33. The lower end 40 of the-rod is preferably provided with a ,keri 41 to facilitate screwing the rod intoor out of the block 28 in eifecting adjustment of the same. The end of the rod is adapted to engage with and be actuated by the sill 24 at the 'time that the sash seats against the sill. When the rod 39 is forced upwardly in the side of the sash by the downward movementy of the latter in seating against the sill, the finger 26 will be forced laterally against the opposed face of a vertically extending member 42 associated with the guide strip 16, causing the sealing strip 17 to be pressed snugly against the opposed wall 18 of the side of the frame, all as clearlyshown in Figs. Zand 3. Y Y

From the foregoing, it will be understood that the sash lO may be raised and lowered without effort in the grooved guides provided at the sides of the frame 1l, and that, when the sash bottoms against the sill 24, the lower ends 40 of the rods 39 will be forced upwardly in the sides ofthe sash and will cause the fingers 26 to project laterally from the sides, thereby forcing the sash outwardly against the outer side walls of the guides. Y The fingers 26 of the sash-tightening devices are preferably located near the upper ends of the sides of the sash in ordery to exert pressure primarily on the upper portion of the sash, especially when locks 43 of the well known throw-over type are mounted on the bottom rail 22 of the sash. The locks 43 have no connection at all with the novel sash-tightening devices 25 of the invention but are merely used in the ordinary way, the noses 44 on the ends of the rock-bolts of the locks being intended to project under spring pressure into l engagement with rack strips 45 housed within the lower portions of the guide strips 16.

In those window constructions wherein the sash-tightening devices 25 are used alone without the supplemental throw-over action of locks at the bottom of the sash, the locations of the devices 25 might be lowered, or else two of the' iingers 26, connected together for simultaneous operation, might be vused at each side of the sash, all for the purpose of obtaining the most advantageous distribution of the pressure on the sides of the sash outwardly against the sides of the frame.

The tightening Ydevices 25 do not interfere in the least with the raising of the sash, releasing immediately as soon as upward pressure is brought to bear on the sash. The devices 25 may be easily adjusted'by merely raising the sash and turning the rods 39 with a screw driver in either direction. If, in connection with'some particular window construction, a small amount of projection of the iingers 26'laterally is suflicient to tighten the sash against the guides, then'the rods 39 will be screwed inwardly in the blocks 28 into positions wherein thelower'ends of the rods will project only a short distance below the rubber sealing strip 23 on the bottom rail ofthe sash.l

If, on the other hand,alarge amount of projectionof the iingers 26 is necessary inorder to obtain-a tight iit, the rods 39 will be screwed outwardly a corresponding distance. As will be noticed, the devices 25, although readily accessible for adjustment, are concealed by the guides.

In Figs. 8 to 10 inclusive, a somewhat diiferent application of the invention is illustrated. In those views, the sash-tightening devices 46 are shown as being housed within the detachable guide strips 47 instead of within the sides 48 of the sash. The vertically extending rods 49 which act to force the upper ends of the fingers laterally into engagementfwith the sash, are pivotally connected at their lower ends to small leverS.

f thereof, a sash slidably mounted in the guides, a

pair of laterally projectible members housed within the sides of thesash for pressing the latter against corresponding sides of the guides whenthe sash is closed, and a pair of operating rods for the members extending downwardly therefrom into positions beneath the bottom rail of the sash for engagement with the sill of the frame when the window is closed, said rods causing the laterally projectible members to press the sash tightly against the guides when forced back up into the sash by engagement with the sill into positions ush with the bottom rail of the sash.

2. In window construction, a frame provided with vertically extending guides at the sides thereof, a vsash slidably mounted in the guides, projectible means adjacent the upper portion of the sash for pressing the sash against corresponding sides of the guides, and means adjacent the lower portion of the sash connected with said first mentioned means for projecting the latter, said second mentioned means being operated automatically by the movement of the sash relative to the frame to project said nrst mentioned means when the sash reaches its closed position.

3.* In window construction, a frame provided with vertically extending guides at the sides thereof, a sash slidably mounted in the guides, a pair of laterally projectible members housed within the sides of the sash above the bottom of the latter for pressing the sash against corresponding sides of the guides when projected, and vertically movable members projecting from the bottom of the sash and connected within the same to the projectible pressing members for automatically projecting the latter upon engagement with the sill of the frame.

4. In window construction, a frame provided with vertically extending guides at the sides thereof, a `sash slidably mounted in the guides, movable sash tightening members, spring means for causing said members to assume inoperative positions while the sash is being raised or lowered,

5. In window construction, a frame provided 'T with vertically extending guides at the sides thereof, a sash slidably mounted in the guides, sash tightening members movably mounted in the side rails of the sash, means for causing said members to assume inoperative positions while the sash is being raised or lowered, and means for automatically causing said members to assume operative positions at the instant that the sash bottoms on the sill of the frame.

6. In window construction, a frame provided with vertically extending guides at the sides thereof, a sash slidably mounted in the guides, movable sash tightening members, means for causing said members to assume inoperative positions while the sash is being raised or lowered, means causing said members to assume linoperative pof sitions While the sash is being raised or lowered, means for automatically causing said members tovassur'nke operative positions 'at the instant that the sash bottoms Lon thesill of the frame, and manually adjustable means accessibleffrom beneath the bottom rail of the sash' when the latter y is raised for varying the time of operation of said last mentioned means with respect tothe posi-- tion of the sash in the frame. Y A

8.
